The Mitsubishi MRS120W60 is engineered as a brake resistor unit, which plays a crucial role in power management for motor applications. It features a resistance measurement of 60 ohms and is rated for active power output of 120 watts. This unit is designed to connect with motor systems operating at a supply voltage of 200 volts AC.
The MRS120W60 functions effectively in ambient temperatures that span from -10°C to 50°C, making it suitable for a range of environments without condensation concerns. Humidity tolerance is another key aspect, allowing operation in conditions with up to 90% relative humidity. Additionally, for users needing storage options, the unit can be safely kept in temperatures from -20°C to 65°C, maintaining integrity during inactivity.
In terms of compatibility, the brake resistor can interface with both 1-phase and 3-phase input applications. Its efficient design supports a motor capacity from 1.5 to 2.2 kilowatts. Moreover, the MRS120W60 is paired with the TH-N20CXHZ-2.1A thermal relay type, ensuring that the system remains protected from potential overload conditions. The permissible brake utilization rate is between 6% and 10%, meaning that it can effectively handle varying loads.
Control torque is rated at 100%, providing precise torque control necessary for effective motor performance. Designed for operational efficiency, the MRS120W60 can be installed at altitudes of up to 3,280 feet (1,000 meters) above sea level, ensuring robust performance even in less-than-ideal mounting locations.
